Unclear in app, but to get more games, you hit new and choose the size of the board and its shape. ### 5/5 — Best Slitherlink game on the App Store *2023-06-28* I’ve played Slitherlink for years and this is my favorite in the Apple market ### 3/5 — So great, but… *2021-07-10* I absolutely love this game and play it all the time, however, there are just two things wrong. 1 - we really need a reset button for the individual puzzles. Sometimes we get deep into a huge puzzle, mess up somewhere and in order to restart have to hit the undo button a thousand times. I know this game does not seem to be under development any longer, but if that one little thing could be added it would be amazing 2 - this one is less important to me, but the download for larger/hard puzzles is painfully long. If that could be improved, great, if not, not the end of the world. ### 4/5 — Desperately seeking dark mode *2021-04-01* Dark mode with neon colored lines would be awesome! ### 1/5 — Broken, doesn’t work anymore *2020-08-26* The “new puzzle” function seems to rely on an external server which is not working, so... no new puzzles. Hope they fix it. ### 4/5 — Start over/Clear screen option *2019-12-22, version 1.1.7* Great game but would be great to if there was a clear screen button ### 2/5 — Missing many features *2019-07-16* No ability to color faces to distinguish inner/outer sides of the loop; no “night mode” ### 1/5 — Rubbish *2019-03-17, version 1.1.5* Awful app, complete waste of money ### 3/5 — Decent Slitherlink game *2018-01-25* I like that it has a few grid options other than the standard square. I hate that as soon as you complete a puzzle it disappears so you can’t admire your completed puzzle. :( ### 1/5 — Literally the most boring Slitherlinks *2017-08-22, version 1.1.1* This is a seriously boring game. Even when set on 'Very Hard', the game is incredibly easy to beat. In other Slitherlinks of the same size, it can take up to half an hour to solve, and actually involve some thought rather than just mindless tapping. Would not recommend spending money to get this lacklustre app. ## Frequently asked questions about Slitherlink Pro ### What is Slitherlink Pro?
